The Love Island hostess was seen wandering around London on Wednesday morning talking into her phone - and wearing her feelings very much on her hand.

Caroline's enormous diamond ring, gifted to her by Apprentice star Andrew just weeks into their rollercoaster relationship, was glinting away on her left hand - prompting speculation their engagement might not be completely over.

An eyewitness told Mirror Online: "She came and picked up a drink from a local cafe then got on the tube.

"She didn't make any attempt to cover up her ring - clearly she's trying to prove a point."

The blonde presenter looked incredible in a pair of black denim cut-off shorts and nude ankle boots to highlight her lengthy legs.

She teamed them with a crisp white shirt tied into a knot at the waist and dangled an on-trend leopard print bag from her elbow.

Caroline looked as though she'd been up for hours, with a slick of perfectly on-point scarlet lipstick on her pout and some aviator sunglasses covering her eyes.

But a closer look shows Caroline was sporting a nasty scratch above her right eyebrow.

She made no move to cover up her ring, which suggests Caroline still thinks there's life in her broken relationship.

Neither she nor Andrew have publicly commented about restarting their engagement after their joint statement about splitting, although Caroline has made her feelings clear on Twitter.

Last night she tweeted a single crying emoji after Andrew told his Instagram followers they'd broken up.

Awkwardly, Caroline's gushing open letter to Andrew is still available in the current issue of Cosmopolitan magazine - something that is no doubt causing more than a little pain.

The unlucky in love star spoke of her dating highs and lows and revealed how things were different with this time around with Celebrity Big Brother star Andrew.

"People talk about meeting someone and feeling as though you've known them your whole life. That's what it felt like when I met you," she wrote in her published letter.

"Talking to you was effortless – just two people laughing and getting to know each other until the early hours. It was how all first dates should be," she added.

Opening up about their bond, Caroline - who previously dated Harry Styles and Prince Harry - said her relationship with Andrew was like nothing she's ever experienced before.

"We laugh until we cry. I've never had that before – with anyone. Every other relationship I've had has only been about love, but with you it's about friendship, too. It's what I've been looking for," she added.

"My life was complete before you came into it – a man doesn't complete your life. But I wanted to make room in it for you. I look at you and I think, 'Yes, Andrew, you're the one I've been waiting for'."
